[jira] Commented: (MCOMPILER-95) no such compiler 'javac' when
compiling code with maven-compiler-plugin maven 2.1.0-M1 in windows Vista
[ http://jira.codehaus.org/browse/MCOMPILER-95?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=171280#action_171280 ]
Benjamin Bentmann commented on MCOMPILER-95:
--------------------------------------------
bq. JAVA_HOME and maven\bin in PATH is properly set .
It would be helpful to know whether the JAVA_HOME used to run Maven actually points at a JDK or just a JRE.
Please run "mvn install -X > debug.log" and attach the resulting log for further analysis, when possible using the latest Maven release version 2.1.0.
In the meantime, you could try setting the plugin's [fork|http://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#fork] parameter to {{true}}.
